概括
升高的前素 (PCT) 水平独立地预测未来的非病毒性肝病风险. 这一发现表明PCT可能是评估肝病风险的有用生物标志物,并可能是肝损伤的直接原因.
科学领域:
- 生物化学 生物化学
- 肝病学 肝病学是一种肝病学.
- 临床生物标志物 临床生物标志物
背景情况:
- 众所周知,在没有细菌感染的肝病患者中,前素 (PCT) 度会升高.
- 以前的研究表明PCT与肝脏健康之间存在潜在联系.
研究的目的:
- 调查高甲素 (PCT) 水平与未来患非病毒性肝病风险之间的关联.
- 为了确定PCT是否可以作为肝病发病率的独立预测指标.
主要方法:
- 在两个大型队列 (MDC-CC和MPP) 中测量了前素 (PCT) 水平,其中包括近8000名没有已知的肝病的人.
- 考克斯的比例危险回归模型被用来分析基于PCT水平发生性肝病的风险.
- 进行了多变量调整模型和队列特异性灵敏度分析,包括C反应蛋白.
主要成果:
- 在对两个队列的综合分析中,高PCT (>0.05 ng/mL) 个体显示患非病毒性肝病的风险显著增加 (HR 3.4,p < 0.001).
- 在日志转化PCT中,每一个标准偏差的增加都与肝病风险增加1.56倍有关 (p < 0.001).
- 敏感性分析证实了这些发现,即使在对C-反应蛋白进行调整后也是如此.
结论:
- 升高的公素 (PCT) 度是非病毒性肝病的独立预测因子.
- 这些发现对肝病风险评估有影响.
- 这项研究表明,前素 (PCT) 可能起到直接导致肝细胞损伤的作用.

1.5K
Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

8.4K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
